Grimshaw previously denied the duo were an item after images of them wearing each other's clothes and frequently spending nights out together sparked rumours.

But Styles is unfazed by the gossip, which he says comes with the territory.

"Some of them are funny. Some of them are ridiculous. Some of them are annoying.

"I don't want to be one of those people that complains about the rumours. I never like it when a celebrity goes on Twitter and says, "This isn't true!" It is what it is; I tend not to do that.

"The only time it gets really annoying is that if you get into a relationship and you get into a place where you really like someone and then things are being written in the papers that affect them and how they see you. Then it can get annoying."

Styles and the rest of the One Direction boys - Niall, Louis, Zayn and Liam - each appear on one of five individual covers for September's edition of GQ.
